[Haskell-cafe] Haskell version of "Monad Transformers and Modular Interpreters"

[Günther Schmidt]

Hello,

I come across the paper "Monad Transformers and Modular Interpreters" 
(http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.17.268) alas 
the code is in Gofer and I'm not certain how all of it translates to 
Haskell.

Are there other papers out there that translate this to Haskell?
